Political positions

Housing Mansfield has supported policies aimed at increasing public and social housing in Victoria. She has been critical of reliance on market-based approaches to housing affordability and has argued for a greater role for government in addressing housing supply and rental costs, including in regional areas. She has participated in public demonstrations calling for an end to the conflict and has urged the Australian government to take action in response to civilian casualties in Gaza. The motion passed 22-15. She has also opposed the Victorian government’s decision to abolish VicHealth as an independent statutory authority, arguing that the move would weaken public health promotion and oversight of harmful industries.

Youth participation Mansfield has advocated for increased involvement of young people in decision-making processes. She has stated her belief that young Victorians’ perspectives are often overlooked, particularly on issues such as housing affordability, climate change, and social equality. Mansfield has described formal parliamentary processes as potentially intimidating and a barrier to youth participation in politics. Mansfield has highlighted the Geelong Youth Council as an example of a mechanism through which young people can formally contribute to local governance. She has argued that young people should be recognised as active contributors to political change rather than being treated simply as future leaders.
